Acetone vs. WD40

O.k., I could just try it out, but I guess somebody else has already done that: I usually use acetone to clean my surfaces before gluing/epoxying or applying a finish (in most cases a mix of tung oil and shellac). Can I also use WD40 for that? Will it affecy epoxy or oil-based finishes?

WD40 is evil stuff. The layers of build up over the years leaves a shelac like coating that is yellow and dingy. Granted I don't have input on your needs but after cleaning tools and equipment over the years treated with this gunk... I'll never touch the stuff again...

WD-40 will leave a thin layer of oil on the pieces you are working on, preventing epoxy for sticking. Acetone is definitely the winner here. Acetone will dissolve the oils on some of the oilier hardwoods, where as WD will leave a film on top of it.
